In some circles yes, but theres alot of web developers that are still on Windows for whatever reason. I am from Germany and people here are less prone to brand marketing and i still see quite alot of people using Windows, even people i highly respect for their skills. Im mainly talking about coders though, not designers.
I will say here, that I am one of those people that do not like OSX. My main issues are getting it to behave with the muscle memory I have developed over years of use with windows and linux machines. Home and End key behavior, actually quitting an application when closed, full-screen apps (though I understand this is fixed in recent OSX builds), and other minor annoyances keep me from fully embracing OSX. I understand that these are personal preferences, and not problems with OSX for the most part.
On the other hand, I REALLY like the idea of an app and all its dependencies being installed all in one folder. That REALLY needs to happen everywhere. This would make migration between installs SO much easier, and would eliminate DLL hell (or shared library hell in the case of linux).
Exactly my thoughts. I use OSX alot for different reasons but i still think i am more productive on Windows/Linux. Keyboard shortcuts and behaviour is consistent as opposed to OSX where its kind of a pain.
I also dont like the dock, i like to have a taskbar with the open windows on each of my monitors which is no problem in Windows and Linux. I dont like the Menubar stuck on the main monitor.
As a web developer i really like the unix base of OSX for different reaons though and i need to use some software for game dev (Unity3D) which isnt available on Linux.
But i thought about running Windows for game dev/office stuff and Linux in a VM for web development.
